To all whom t may concern.-

Bc it known that I, EDUARD Koene-R, a citizen of Germany, (wholiasdeclared his intention to bccoine a citizen of the United States,)and resident ofl Jersey City, in the county of Hudson and State of NewJersey, have invented certain new and useful linprovenients in GearCases, of which the following is a specification. f

This invention relates to gear cases for and efectua-lly counteract thesevere lateral and torsional strains to which the case iS subjected,therebyinsuring the rigidity and increasing the durability andgeneraletV iciency of the structure. Y

In the preferred embodiment of my in-y vention herein illustrated thebody of the gear case comprises two complementary trough-shaped sectionsof oval form in crosssection, each section being an integral sheet metalstructure. The .ends of the respective sections have aixed theretosubstantial brackets of special construction which not only effectuallyreinforce the case but also provide rigid end supporting jaws which arereliably yet detachably coupled, as will be hereinafter fully set forth.The precise scope of the invention will be defined in the appendedclaims.

In the drawings- Figure l is a front elevation of my iinproved gearcase, the supporting arms therefor being shown in section.

2 is a plan of the gear case.

Fig. 3 is an end elevation of the structure.

Referring to the drawings, 5, 5 designate two trough-shaped sections,each of which comprises an integral sheet metal structure. The twobodies, of which one is the counter-v part 'of the other, are fittedtogether edge to edge to provide a shallow casing of suitable size andformto contain the interineshing gears of the power transmitting mecha,

nism for the vehicle to which the case is apgear cases for electricmotorl plied. erably of oval forni in longitudinal section. Thelongitudinal' edges of the two sections are provided with correspondingsemi-cir- The casing' thus provided is prefcular recesses 6 which, whenthe sections are united, provide in'botli sides of thestructure'opposite circularv openings for the passage of the shaft oraxle carrying-the driven gear wheel." The ,edgeV of the openingin en lthat side ofthe case adjacent the inotor, is

preferably reinforcedby an annulus 7 which is riveted or otherwisesecured to the adjacent walls of the two'sections..` Thesectionsvai'ealso provided on the side adjacent the motor with correspondingsemi-circular recesses 8 which affordan opening forthe'l entrance ofthe'inotor shaft to the yrase," Vwhich shaft carries. the driving gearwheel.

The sidewalls of one of the sections, in the-:present instance theuppersection,V has aHiXed thereto, by rivets or weldingflongi; tudinallydisposed strips 9 ,which provide flanges that overlap the adjacent edges'of the other'o'r lower section and thus prevent, Y

lateral displacement vof the yassociated.secg,

tions.

lateral thrust flange 12 which-.overlaps theV u side of the'sectionadjacent the niotorl and is riveted to such side, as at 13; an outwardlyprojecting perforated portion 14 constituting a jaw member, and lateralrein- On each'sectioii, adjacent its respective, ends', are inountedland secured two stoutfl brackets which project endwise from thesecforcing ribs 15 which connect suchprojecting portion with the body ofthe bracket` The two brackets at Veach end of the case are suitablyspaced apart so that the upper and lower jaws '14 embrace'-the adjacentsupporting arm (16) projecting from lthe y l motor case or other fixedportion of the vehicle. The jaws are'rigidly secured to the respectivearms by throughfbolts 17.

The construction just described provides reliable suspension deviceswhich eifectually reinforce the respective ends ofthe case in suchfamanner as to counteract the severeV lateral and torsioi'ial strains towhich the structure is subjected 'at and adjacent its points of support;and the structure as a Whole combines the advantages of rigidity.,strength, lightness and durality.

In the present instance suitable coupling members are `applied to thejavvs let at the respect-ive ends ot' the'structure, and such j aws, inconjunction With the coupling members, are secured to the respectivebars by the bolts 1T. Each of the coupling members illustrated comprisea yoke-like device having a body 18 with upper and loiver angular endextensions 19. These' extensions arc perforated for the passage of thebolt 17 and the upper extension has struck up therefrom two spaced-apartlugs 2l between vwhich the head ot' the bolt is seated, suoli lugs thusserving as a lock t'o prevent accidental rotation of the bolt. Theselugs areV also provided with perforations for the passage of a` cotterpin 22, Which, overhanging the head of the bolt, prevent accidentalre-'z moval of the latter should the nut QSthereot work loose. l

It is to be understood that my invention is no t limited to the exactdetails ofconstruction hereinV .disclosed ask modifications may be madeWithin the principle ot the invention and the scope of the appendedVclaims. i

I claiml. In a gear case adapted to be Suspended at its ends from spacedsupports, tivo troughlike sections, veach comprising Van integral. rimand sides, exterior brackets atixredV to each section adjacent thelrespective ends of the rim, each of saidbrackets comprising a bodymounted on the'rim and having whereby each pairvof adjacent jaws thusprovided ar'e secured to a support embraced thereby.

2. n a` gear case adapted .to be suspended at its ends from spacedsupports, vtwo trough-like sections, each ,comprising an integ-ral rimand sides, exterior brackets atiXed to each section adjacent therespective ends of the rim, each ot said brackets being an integralcasting comprising a body mounted onthe rim and having 'a lateral thrustilange which overlaps the adjacent side of the section,` and also havingan end- Wise projecting jaw member and lateral rein- 'lorcing ribs whichconnect said vmember with the body of the bracket, and means wherebyeach pair of adjacent jaivs thus provided are secured to a supportembraced thereby. Y

In a gear case adapted to besuspended at its ends from spaced supports,tvfo trough-like sections, each comprising an integral rimandlsides,exterior brackets affixed to each section adjacent the respectiveends of the rim, each of said braclretscom.

prising a body mounted"V on the rim` and having a thrust portion Whichlaterally over-4 laps thesection and also having a jawwhich projectsendwise beyond ythe section, a detachable coupling device .foreach :pairof ad jacent jaws thus provided at yeach end of the case, and means forsecuring eachv pair of'jaws and their associated coupling dewiretogether and to a support embraced by said aws.
